It must be something in the arid Houston air that makes the biggest rappers also some of the best entrepreneurial minds that hip-hop has seen.

Before being nationally renowned as a rapper, Paul Wall was working in the promotions department at the legendary Swishahouse with fellow Houston emcee Chamillionaire. A placement on the imprint's mixtape made both rappers rise in stock amongst the Houston mixtape crowd.

In 2005, Paul Wall released his major label debut, 'The People's Champ,' under Swishahouse/Atlantic and hasn't stopped working since. When he's not designing diamond encrusted grills with his partner Johnny Dang, he's still on the mic. In 2012, he released the 'No Sleep Till Houston' tape to positive reviews.
